[Paraview] reading MATLAB file

[Mauro Fontana]

Hi Randy

I'm not sure if it is what you are asking, but this might be useful:
https://blog.kitware.com/easy-customization-of-the-paraview-python-programmable-filter-property-panel/
.

That way you can have a GUI field for the path of the .mat file to read,
much more convenient that changing the path in the code each time.

Cheers,
